Getting "Unable to read data from the transport connection" exceptions on every request

[daveaglick]

I'm excited to get uHttpSharp working - the simplicity of design is exactly what I'm looking for. However, I've got a simple example up and running and keep getting a System.IO.IOException with the message Unable to read data from the transport connection: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond. after every request (it's showing up in the trace output).

Here's my code:

HttpServer httpServer = new HttpServer(new HttpRequestProvider());
httpServer.Use(new TcpListenerAdapter(new TcpListener(IPAddress.Loopback, _previewPort)));
FileHandler.HttpRootDirectory = _engine.OutputFolder;
httpServer.Use(new FileHandler());
httpServer.Use(new ErrorHandler());
httpServer.Start();

And here's the trace output:

Any ideas what I'm doing wrong?

Also, on an unrelated note I noticed this is forked from int6/uhttpsharp, but this fork seems to have more activity and is the one referenced from NuGet. What is the relationship between the two repositories?

Thanks!

[shanielh]

I'm not sure you're doing anything wrong. I'll check it out this weekend. This repository forked from int6/uHttpSharp and had major refactors to adapt to the structure of koa.js.

I hope you'll enjoy to use uHttpSharp.

Hey mate. Thanks for the bug, I managed to fix it. It happened because I set the read timeout to one second, And google chrome and other browsers open up more than one connection when connecting to a server (I guess it's sort of a "Connection Pooling").

A new version is up (0.1.6.20) in nuget.

[daveaglick]

Thanks!

[mateuszbyczkowski]

I have the same problem and this solution doesnt work for me. Any ideas?
Its throwing exception System.NET.Sockets.SocketException Establish connection was aborted by software installed on host-computer.
SocketErrorCode = ConnectionAborted.
Iam making several requestes for RTSP stream and displaying it in chrome browser, and encounter problem when iam trying to run video. Stream is actually working (iam able to see video playing) but i have many exceptions of Socket, that i want eliminate.

Thanks for help.

[AliFlux]

Hi. That error occurs when the client aborts the connection (could be due to any reason at all). Is there a way to catch this error so that it doesn't bug.

Thanks.

[AliFlux]

Any update on this?
